Box-CLAMP'ING DEVICE.

Application filed April 7, 1926. Serial No. 100,342.

My invention relates to improvements in means for holding the covers of paper boxes while being sealed. It has for one of its objects the elimination of machines to which boxes are brought to have the covers held on under pressure to effect sealing. Another object of my invention is to supply a device which is convenient to handle, portable, and to assist substantially in a process of sealing a large number' of cardboard, corrugated and fibre boxes and shipping cases. A `further object is to create a cheap method of satisfying the need of holding the flaps of stiff cases down until the mucilage or gum paper is fixed. More spcciiically my invention relates to a clamp for holding down the covers of collapsible fibre boxes and shipping cases untilv they are sealed.

While in the annexed drawings only a pary tiicularfoi'm of my invention is described and illustrated the mechanical equivalents and methods by which the same results are obtained are within the contemplation of my invention.

26 In said annexed drawings:

Figure 1 shows a side elevation of the clamp in its collapsed form when not in use;

Figure 2 illustrates a side elevation of t-he clamp in its expanded posit-ion when it is applied to a box for holding down the iaps while being sealed; l

vFigure 3 shows a side elevation of the clamp;

Figure 4 consists of an enlarged plan view $5 ot the adjusting bolt taken on the line IVMIV, Figure 2;

Figure 5 represents an enlarged' vertical section of the adjusting bolt on the line VMV, Figure 2; and i Figure 6 illustrates a vertical section taken on the line VI-VL Figure 5. showing the adjusting bolt in its locked position.

Referring to the same elements by the same ordinals throughout the several views,

U5 I'designate a straight bar with the ordinal i 1 at one end of which is pivoted the arm 2 mounted on the rivet 3 traversing the arm 2 and the bar 1. In order to present a Hat surface at its lower part the arm 2 is twisted through an angle of 90 degrees somewhere near its center where an eyelet 4 is riveted to the arm 2. Beneath the eyelet a finger 5 formed to make a right angle with the arm 2 at its lower intersection is riveted to the arm 2 at the points 6. On the outer side of the arm 2 a handle 7 is riveted at the points 8.

The opposite end of the bar 1 is provided with indentations 10 having narrow necks 10 spaced as desired on the upper edge ci the bar 1 as plainly indicated in Fig. 1. An arm 2 similar to arm 2 and similarly itted with an'eyelet 11, finger 5 and handle 7 riveted at the points 8 has in place of an ordinary rivet a bolt S) held in place by the wing nut 15 as shown in Figure 5. The portion of the bolt passing through the opening 10` has its sides cut away, as is plainly shown in Figure 5. By means of the narrowed section the bolt 9 is slipped into one ot' the indentations 10 by way o'li the narrow necks 10. The nut l5 need not be removed to change from one notch to ann other because of the thinned section of the bolt 9. To lock the bolt in the desired notch the bolt 9 is turned by means of its flat head through an angle of degrees into the position shown in Figure 6 so that the bolt forms a. pivot for the bar 1 and the arm 2.

The arms 2 and 2 are connected by means of the spring 11 which normally tends to hold the component parts of the clamp in the position indicated in Figure 1.

vWhen it is desired to use the clamp the effective length ot the bar 1 is adjusted to the length of the width of the boxes upon which the clamp or clamps are to be used. By means of the handle 7 and 7. the arms 2 and 2 are pulled outward and slipped over the sides of the box 141 until the fingers come in contact with the top l2.

lVhen a case has been loaded two of the four sides are folded over, forming the suriface 13. This surface is coated with mucilage and the other iiaps are folded over. Because ci the stiffness of new boxes the flaps tend to fly away from this position and to prevent this action until the glue is set a pair oit clamps are slipped over the box as indicated in Figure 2 to hold the flaps until fast. v

The clamps obviate the necessity of applying cumbersome weights or of moving' the boxes to a machine for sealing. With about a halifdozen pairs .of clamps a con-- tinuous process of sealing can be maintained because by the time the last box is clamped and sealed the rst one is tast and the clamps may be removed and used on another boX.

YWhat l claim is:

l. A box-sealing device conn'irising in combination a rod; an arm pivotally attached to one end oi said rod; a similar arm adjustably and pivetally attached to the opposite end ot said rod; resilient means aHined to both ot said arms tending to bring said arms together; fingers perpendieularly fastened to the opposite inner surfaces et said arms and being on opposite sides from said rod relative to said resilient means; and handles al'lirzed to the outer surfaces of said arms.

2. A box-clamping device comprising in combination a rod; an arm pivotally swing ing on one end of said rod; a similar arm engaging slots With necks and situated at spaced intervals near the opposite end of said rod by means of a bolt having lateral indentations enabling said bolt to by-pass the necks ot said slots and preventing egress ot said bolt when the latter is rotated through an angle of 90 degrees; resilient means atlixed to both oi said arms tending to pull said arms together; fingers perpendicular-ly Yfastened to the opposite inner surfaces of said arms; and being on opposite sides trom said rod relative to said resilient means; and handles atiixed to the outer' surfaces of said arms.

3. A boxeclamping device comprising in combination a rod; an arm 'pivotally swinging on one end ot said rod; a similar arm engaging slots with necks and situated at spaced intervals near the opposite ends et said red by means of a bolt having lateral indentations enabling said bolt to by-pass the necks oli' said slots and preventing egress of said bolt when the latter is rotated through an angle et 90 degrees; fingers perpendicularly Yfastened to the opposite inner surfaces o't said arms intermediate the fingers and the pivoted ends and tending to pull said arms together; and handles affixed to the outer surfaces ot said arms.

4. A box-sealing device comprising in combination a ron; an arm pivotally attached to one end et said rod; a similar arm pivotally attached to the opposite end ot said rod; resilient means aiixed to both of said arms tending to bring said arms together; fingers perpendiculariy fastened to the opposite inner sur'l'accs of said arms and being on opposite sides Yfrom said rod relative to said resilient means; and handles allixed to the outer surfaces ot said arms.

5. i portable box-clamping device comprising in combination a rod; an arm pivotally swinging on one end ot said rod; a similar arm engaging slots with necks and situated at spaced intervals near the o pposite end oi said rod by means ot a bolt having lateral indentations enabling said bolt to by-pass the necks ot said slots and preventing egress et said boit when the latter rotated through an angle ot 90 degrees; tingers perpendicularly fastened to the opposite inner surfaces ot said arms; resilient means aliiXed to .both ot said arms intermediate the fingers and the pivot-ed ends and tending to pull said arms together; and handles at' :fixed to the outer snrtaces ot said arms.
